The Link Quick Release Adapter for Simucube 2 lets an existing Simucube 2 wheelbase use the newer Simucube Link mechanical quick release. It is a useful upgrade when you want the P3G locking interface without replacing a working wheelbase—but it does not turn Simucube 2 into a full Simucube 3 Link system. This guide explains exactly which parts are required, what still works wirelessly and what to check before removing the original SQR.
What the adapter changes—and what it does not
The adapter replaces the original wheelbase-side Simucube 2 quick-release interface with the base-side part used by the newer Simucube Link Quick Release. Simucube describes the Link mechanism as a stress-optimised conical P3G polygon lock designed for a rigid, rattle-free connection and quick self-centering attachment. The adapter package includes the SC2 adapter, the Link male part, mounting screws and 3 mm and 4 mm hex keys.
The limitation is electronic. Simucube 2 cannot use the Link system's Lightbridge wireless power and data transfer through this adapter. A traditional Simucube Wireless Wheel can continue communicating by Bluetooth as before, while a USB wheel still uses its own cable. The Simucube Link Hub does not change this physical limitation at the SC2 shaft; do not buy it expecting the adapter to power a Link wheel through Simucube 2.
Parts checklist before you start
- Wheelbase side: one Simucube 2 Link Quick Release Adapter. The supplied male Link part is fitted to the wheelbase assembly.
- Wheel side: one Link Quick Release for every steering wheel you want to use with the new interface.
- Wheel mounting pattern: a 70 mm six-bolt steering-wheel interface is directly supported by the Link wheel-side. A 50.8 mm formula pattern needs the separate 50.8-to-70 mm adapter specified by Simucube.
- Wheel electronics: Bluetooth for a compatible Simucube Wireless Wheel, or an external USB cable for a USB wheel. Link power/data transfer is unavailable on Simucube 2.
- Workspace: a clean bench, correct tools, good lighting and the official instructions open before disassembly.
If you have several wheels on the original Simucube SQR wheel-side, count the cost of a new Link wheel-side for each wheel. The conversion is most attractive when you use one or two main wheels; a large SQR collection can make the total migration cost considerably higher.
Compatibility check: steering wheel, bolt pattern and cable
Inspect the rear of the wheel instead of relying on its product name. For a 70 mm pattern, confirm whether the wheel uses threaded holes or unthreaded through-holes; the Link wheel-side provides mounting routes for both types, but the correct holes and fastener direction differ. Do not reuse bolts of unknown length: an overlong fastener can bottom out or damage internal parts, while a short one may not provide enough thread engagement.
Next, plan the data cable. A Simucube Wireless Wheel can retain its conventional wireless connection on Simucube 2. A third-party USB wheel needs safe cable routing with enough slack for steering rotation but no loop that can catch a paddle, monitor bracket or emergency-stop cable. If the wheel itself is Link-compatible, its mechanical attachment still works, but Simucube 2 cannot provide the Link wireless power/data features.
Installation sequence
- Power down completely. Stop the simulator, switch off the wheelbase and disconnect power and USB. Remove the steering wheel and place it on a protected surface.
- Document the original installation. Photograph the existing SQR, spacers and shaft orientation. Keep removed screws in a labelled container in case you later return to the original system.
- Remove the original wheelbase-side SQR. Follow the official Simucube 2 adapter guide and use the specified tool. Support the part as the final fastener is removed; do not lever against the motor shaft.
- Fit the SC2 adapter and Link male part. Start all supplied screws by hand, align the interface squarely and tighten in the order and to the values stated by Simucube. Do not copy Simucube 3 torque figures onto a Simucube 2 adapter step unless the SC2 guide explicitly instructs it.
- Install the wheel-side Link QR. Match the correct threaded or through-hole route for the wheel, use approved fasteners and confirm that no cable is trapped.
- Test mechanically before power-up. Attach and remove the wheel several times. It should self-center and lock positively without visible movement. Check that the release can be operated without striking the dashboard or wheelbase mount.
- Reconnect and test at low torque. Verify steering, buttons and paddles in software, then run a short low-force session before returning to your normal force-feedback profile.
Cockpit clearance and added length
The adapter changes the stack of components in front of the motor shaft. Before installation, measure the current distance from the wheel rim to the seat and monitor. After fitting the adapter, recheck wheel reach, paddle clearance and whether the rim blocks part of the display. A small change in shaft length can require moving the seat or wheel deck, especially in a compact formula position.
Route USB or charging cables only after the mechanical position is final. Turn the wheel through the maximum rotation used in your simulations while watching the cable. Leave controlled slack near the wheel, secure the fixed section to the cockpit and keep it away from the quick-release locking area.
When to convert—and when to keep SQR
Convert if you want the newer locking action, plan to standardise future wheels around Link and own a manageable number of rims. Keep the original SQR if it is secure, you have many wheel-side kits already, or you specifically expect Link wireless power and data on Simucube 2. That last feature requires compatible newer Link hardware and cannot be added by this mechanical adapter.
The Link Hub is relevant to the wider Link ecosystem and device networking, but it is not a substitute for the SC2 adapter and it does not remove the Simucube 2 power/data limitation. Treat the mechanical conversion and Link-network planning as two separate decisions.
Frequently asked questions
Do I need both the SC2 adapter and a Link wheel-side?
Yes. The adapter changes the wheelbase side; each wheel needs its own compatible Link Quick Release wheel-side.
Will Link wireless power work on Simucube 2?
No. Simucube explicitly limits the SC2 conversion to the Link mechanical function. Traditional Bluetooth communication can continue for supported Simucube Wireless Wheels.
Can I keep using an existing USB steering wheel?
Yes, if its rear mounting pattern is compatible with the Link wheel-side and its USB cable is routed safely. The quick release supplies the mechanical connection; the wheel keeps using USB.
Is a 50.8 mm formula wheel directly compatible?
Not directly. Simucube specifies a separate 50.8-to-70 mm adapter.
Recommended purchase order: verify the wheel's rear pattern, buy the SC2 Link adapter, then add one Link wheel-side for each wheel you will convert. Technical sources: Simucube product page and Simucube Link Quick Release guide.
